OTG Exerciser (Optional)

Define OTG Device Configuration
Programming the OTG device is performed in the dialogs of the Device
Structure and Class Request\Other Descriptors tabs. The procedural steps for
programming is identical to that described for Device Emulation starting on
page 130.
Differences from Device Emulation
The OTG DRD Setup dialog opens with a default hierarchy as shown in
Figure 109. You can add configurations to total 3. Each configuration by
default opens with one interface. You can add interfaces to total 2 per
configuration. Each interface by default opens with one Alternative Setting
with one endpoint. You can add Alternative Settings to total 3 for each
interface, but no more than 3 total for the Device. A Device is limited to a total
of 4 endpoints. You can enter descriptor values at each level of the hierarchy.
In addition to support for most standard requests defined for OTG, you can
configure the Device to respond with up to four arbitrary standard request data
descriptors and up to seven String Descriptor strings and to acknowledge up
to eight class requests.
Note To make the just-defined project the Default Project, click the Save button on
the main toolbar. However, to leave a previously defined Default Project intact,
click File on the main toolbar and choose Save As to save the project with a
new name.
Starting a Session
Once you have configured the device and completed an exerciser program,
you must activate the device by clicking the Activate Device button.
Note: After a session starts, the status bar displays:
When a device is active and you change any parameter on any tab, you must
reactivate the device, by deactivating and then reactivating the device.
Note: Device Emulation and the OTG Exerciser may not be active at the same time.
To start a session, click the Start Session button or Wait for DUT (B-Device)
to initiate SRP (If SRP has been checked).
